What was the time when humans were existing with dinosaurs?
Humans never existed with the Dinosaurs. While the dinosaurs lived the largest mammals were about the size of modern rats and were mostly nocturnal (active while the dinosaurs slept). It was not until all of the dinosaurs had died that mammals could risk coming out of hiding during the daytime. The dinosaurs had been dead for about 10 million years before the first primates evolved, and humans evolved from primates about 54 million years after that (dinosaurs had been dead roughly 64 million years before the first humans lived).
Are cats older than dinosaurs?
No, dinosaurs existed before mammals. Reptiles and amphibians existed as long ago as 359.2 million years ago, while the first mammals didn't appear until 251 millions years ago.
Did primates evolve before dinosaurs became extinct?

Where elephants here before dinosaurs?
Mammals did not evolve until dinosaurs were prolific when they did appear they were very small and very scarce when dinosaurs died out.
Did the mammals live before or after the dinosaurs?
The first mammals appeared in the Triassic Period of the Mesozoic Era, when dinosaurs had already been present for at least 9 million years.
Were there animals on pangaea?
Yes, there were animals on Pangaea. Fossils and other evidence indicate that a variety of animal species inhabited Pangaea, including dinosaurs, early mammals, reptiles, and amphibians. These animals evolved and diversified across the supercontinent before its eventual breakup.
Did mammals appear in the fossil record before dinosaurs or after?
Mammals appeared in the fossil record before dinosaurs, with the first mammal-like reptiles evolving around 300 million years ago. Dinosaurs evolved later and became dominant during the Mesozoic Era, while mammals diversified and evolved into various forms alongside dinosaurs.
Were frogs around during the time of the dinosaurs?
Frog fossils have been found dating to the Jurassic period. The Jurassic period was the middle period in the middle of the Mesozoic. The Mesozoic was the era in which all dinosaurs lived, so frogs and dinosaurs did coexist.
